Mrs. Diaz began volunteering in the Regis Library back in the early 1980's. She helped with whatever was needed, whether it was labeling books, cleaning shelves, or watering plants. Each day of her service to Regis would conclude with daily Mass at Saint Ignatius Loyola Church before traveling home. Mrs. Diaz retired from her volunteer service at Regis in 2007.

Over the years, Mrs. Diaz developed close friendships with faculty, staff, and students who would see her on a daily basis. She always spoke to students and staff about how much she loved Regis, and how much the school had meant to her and her family.
